Harmonic Response Analysis

Modal analysis of machine center was carried out by means of finite-element analysis (FEA) method to get its characteristics and to improve its machining precision. Based on this, harmonic response analysis was processed to evaluate its vibration when the cycle load caused by the machining force was applied on the main shaft of machine center, which was used to provide clues for avoiding resonance vibration and ameliorating design.

This paper studies structural topology optimization, and the position of mode shape nodal lines is introduced to the equation as a constraint firstly. It builds the sensitivity equation of the position of mode shape nodal lines and frequency. Thereafter, the element deletion criterion with frequency and position of mode shape nodal lines constraints is afford. Then on the base above, it provides the fit path of topology optimization with constraints of frequency and the position of mode shape nodal lines. Finally, a numerical example demonstrates that the method used in this paper is effectively.

This paper was combined with the third Huaian pumping station to study the dynamic characteristics of the bulb tubular pumping station. By using dynamic finite element analysis method to create Huaian pumping station modes. Then using ANSYS Model Analysis and harmonic response analysis, the vibration modes and dynamic response were researched deeply. According to the mode analysis results, the fundamental frequencies of upper pump house were determined for 1.36Hz and the fundamental frequencies of substructure were determined for 20.11Hz. The dynamic response of the bulb tubular pumping station structure under fluctuating pressures is calculated by ANSYS harmonic response analysis, and the results show that dynamic displacement satisfied the maximum allowable of architectural construction permission，so it can satisfy design requirement, which provides references value for other tubular pumping station in anti-vibration design.

Gust Response

At present, the wind-induced response analysis of an overhead conductor is mainly based on the action of horizontal normal wind. However, for crossing hillsides or extremely strong winds, such a conductor will bear the action of updraft wind, which will change the geometry of the conductor and make its structural dynamic characteristics nonlinear to some extent. In this work, the in-plane and out-of-plane two-dimensional nonlinear equations were established under the action of self-weight and updraft wind. Furthermore, the improved equations of conductor tension and sag were obtained, and the wind-induced vibration response was further investigated. The results showed that the updraft wind caused the nonlinearity of the tension and sag of the overhead conductor, and the nonlinear geometric change significantly affected its resonance response, which exceeded 25% if the wind speed was 50 m/s. In addition, because the proportion of the resonance response in the total wind-induced response was different, the influence of the wind attack angle calculated using the gust response factor method on the gust response factor was slightly larger than that calculated using the the American society of civil engineers method.
